Superior Brightness 
The precision-aligned high-output laser source in this projector features zero-deviation alignment of BlueCore laser diodes to boost luminous flux into the light tunnel for improved light efficacy.
Exclusive BlueCore Technology
The world’s No.1 DLP brand BenQ expands its full line of innovative BlueCore laser projectors for fixed lens installation with this projector, enabling authentic sports matches, enthralling outdoor cinemas, or impactful entertainment in sports bars or private guesthouses.
4K UHD Image Quality for Flawless Presentation 
This projector produces 4K UHD 3840 x 2160 resolution with 8.3 million distinct pixels for each frame, which is four times the resolution of Full HD 1080p, delivering awe-inspiring clarity and crisply defined details. Plus, it utilizes revolutionary 0.47” single-DMD DLP technology to maximize the projector’s sleek, compact profile.
Amazing Color Accuracy
This projector’s powerful BlueCore laser projection utilizes a dual color wheel system to produce unparalleled color performance that achieves a 92% Rec.709 color coverage. By increasing color ratios and the purity of RGBY color, this projector dramatically enhances color saturation to ensure superior presentation quality.
Reliable DLP Technology 
BenQ BlueCore laser projectors are based on the absolute reliability of the 1-chip DLP design. The highly durable DLP chip can last over 100,000 hours without degradation, ensuring true-to-life colors and pristinely legible text over countless uses.
Optimize Image Quality with 4K Image Amplifying
To ensure the best image quality, this projector adopts cutting-edge 4K Image Amplifying Technology to further enhance the quality of projected images. Plus, it automatically upgrades the resolution of all projected images to 4K, guaranteeing superb image details. Additionally, this projector also comes with Pixel Enhancer 4K, a motion-adaptive edge enhancement feature that detects changes in the color between an object and its background to produce sharp edges and precise surface textures.
Liquid Cooling Systems
Advanced cooling systems to ensure optimal thermal conduction during operation. The circulatory liquid cooling system protects the laser light source and DLP engine even after constant operation, while the heat pipe cooling system cools the DMD chip.
Long-Lasting 20,000 Hours Performance
BenQ BlueCore laser projectors deliver 20,000 hours of superior image quality and performance. The laser light source resists color decay over time, making BenQ laser projectors ideal for multiple blending projections without concern for adjacent projectors generating different levels of brightness after a period of operation.
Superior Dustproofing for Severe Conditions
Designed with sealed laser modules and enclosed light engines to protect the DMD chip, color wheel sensor, laser light source, and other optical components, this projector is made to last. This lock-and-key design hermetically seals the engine from dust* to prolong projector lifespan.
Laser-Powered Ultra-High Contrast
Create strikingly clear images with a high 3,000,000:1 contrast ratio for true deep blacks, vivid rich colors and fine subtle details. This projector also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
360° and Portrait Projection for Diverse Spaces
BlueCore laser technology guarantees reliable projection from any angle. Dynamic installation options such as 360° rotation and portrait orientation allow projection onto ceiling, walls, floors, or angled signage.
